OIL BURNER FOR. HEATERS.

Application filed December 11, 1923. SeriaLNo; 679,922.

To all whom it may concern:

Be it known that I, PETER Torr, a citizen of the United States, and aresident of Philadelphia, county of Philadelphia, State of Pennsylvania,have invented certain new and useful Improvements in Oil Burners forHeaters, of which the following is a speci fication.

The present invention relates to burners using oil as a fuel, and whichare to be employed with hot air heaters, hot water or steam heaters, orany other heater for house heating purposes.

Some of the objects of the present invention are to provide a simple,economical and practical oil burner for use in furnaces of the typeheretofore using coal or wood as a fuel; to provide an oil burner soarranged and constructed as to completely vaporize the oil as it issupplied to the burner and eliminate smoke; to provide an oil burner solocated and arranged with respect to the air supply as to operatewithout the odor usually present in oil burners; to provide an oilburner construction in which the oil is supplied to the burner andburned without the undesirable roar or noise of the combustionftoprovide-an oil burner and supply system therefor which operatesas a unitwithout requiring hydraulic or electric pumps or any other pressureproducing mechanism; to provide an oil burner in which the fuel issupplied in regulated quantities by gravity, and can be adjusted to givea desired burner temperature; and to provide other improvements as willhereinafter appear.

In the accompanying drawings, Fig. 1 represents a side elevation, partlybroken away, of a heater system embodying one form of the presentinvention; Fig. 2 IBPIB', sents a plan of the burner of the presentinvention; Fig. 3 represents a section on line 33 of Fig. 2; Fig. 4represents a sec tional elevation of a form of water heater embodyingthe burner of the present invention.

. Referring to the drawings, one form of the present invention is shownin Fig. 1 as installed in connection with a heater or furnace 10 whichis of the hot air type,

' having a grate 11 of the usual form, and to nected to the ordinarycoal burning furnace without dispensing with any of its parts or makingany material alteration in its construction and operation, though itwill be understood in someinstances the present, in-

vention will befurnished with its own cas- As a means for supplying heatunits to the furnace, a burner 13 of novel formof construction isprovided, consisting of a shell .14'closed at its bottom and sides. butopen at the top for the purpose of receiving the burner unit 15 and alsofor serving as ameans for directing the flame upward and concentratingit in the desired manner. The shell 14 is preferably of substantiallyoval shape, and is formed of a special cast alloy to withstand theintense heat to which it is subjected, and the fact that when the burneris in use it becomes highly heated serves to increase the eifectiveheating area of the burner. The burner unit 15 consists of a copperpipeor other pipe 16 of suitable material, which enters the top of theshell 14, where'it is directed substantially horizontal or parallel tothebottom of the shell in the form of two pipe ,convolutions arranged insuperposed relation, the lower of which terminates in a closedend andhas a plurality of burner outlets 17 in two opposite side walls. the oilfuel inwardly and upwardly into the free space of the oval, so that'thetwo series of inwardly directedjets meet, and combine to produce averyintense, perfect-burning flame. This burning of the oilvapor is madepossible by the provision of an air inlet 18, located at the lowerportion of one end of the shell 14, and; by the provision'fof a sec- 0ndair inlet 19, located at a diiferent point in the wall of the shell 14,and in relatively close proximity to the top thereof. It has been foundby experiment that a burner so constructed and having its air inlets atop posite ends of the shell 14, one being ,relatively near the bottomandthe other'rela tively near the top, gives a combustion which is freefrom odor, smoke and noise. Thus, by properly positioning the inlet 1.8in substantially horizontal alinement with the lower convolutions oftheburner coils, the air which here enters mixes with the oil vapor at themoment of its egress from the outlet 17 and produces a mixture whichburns clean and free. The rising productsfr'oii the burner incidenttothis combustion are These outlets 17 serve to discharge then met byair entering by way of the upper inlet 19, so that any oil or othercombustible products rising with the flame and otherwise unconsumed arecaused to be ignited by the freshentering air, and thus finallycompleting the combustion and making use of all of the available heatunits.

In assembled condition the shell 1a is arranged to be supported upon.the grate-11 of the heater, thus taking the place of the bed of fuelheretofore employed, while the liquid fuel is supplied to the burner byway of a supply pipe 20, which for convenience trav erses an opening 21formed in the furnace door 12. It will be understood, however, that thispipe may be brought in at any desired point in the wall of the heater,so long as the oil is properly fed to the burner. As here shown, thesupply pipe 20 extends exterior of the heater 10, where it is joined toa feed pipe 22 leading from the bottom of an oil or other liquid fueltank 23, which is located at a convenient height above the burner 15, sothat the oil will flow freely by gravity from the tank by way of thefeed pipe 22 to the burner. In the present construction, the fuel tank20 is designed to hold approximately twenty gallons of fuel, butnaturally the size of this supply tank is subject to' variation to suitconditions.

In order to control the supply of fuel to the burner, a main controlvalve 24' is located at a convenient point for manual manipulation inthe feed pipe 22, while at the point of juncture of the feed pipe 22 tothe supply pipe 20 a needle valve 25 is provided, by

means of which the quantity of oil entering the supply pipe 20 can beadjusted to-meet the requirements. In Fig. 4 of the drawings, thepresent invention is shown and applied to a heating structureparticularly arranged for use with the present burner, where a hotwater, vaporor steam system is to be employed. In thisform, the burnerunit 15 is located in the'bottom of a casing 26, which is relativelysmall in size, and has a smoke flue 27arranged to be connected to achimney to better feed the products from the burner. In the upperportion of the casing 26 are located the coils 28 and through which thewater to be heated for the heating system circulates and finallytraverses an outlet pipe 29, which is located directly in the heat zoneof the burner. A unit of this kind can also be employed for steam orvapor heaters, as will be understood.

In the operation of the system, the fuel tank 23 is filled with theproper grade of liquid fuel and the valve 24 opened wide to permit afree flow to the feed pipe 22. IVith the needle valve 25 adjusted to therequired opening, the oil will now pass to the burner, and when lightedwill burn with great intensity, thereby not only maintaining the burnercoil heated to produce vaporization of the enteringoil liquid, but alsoto heat the shell 14, and maintain it substantially red hotduring theoperation of the burner.

It will now'be apparent that I have devised a complete unitary oilburning. system which is simple in construction, cheap to manufactureand efficient in operation, which system is readily installed with anytype of furnace or heater now in use to take the place of the heatingmeans theretofore employed. Furthermore, the burner and its adjuncts areso constructed that there is no noise accompanying the burning of thefuel, while odors and smoke are dispensed with by the provision ofsuitably proportioned air inlets in the shell of the burner. It is alsoto be noted that the burner structure includes a receptacle which is,brought to a state of substantial incandescence without melting ordisintegrating. This is an important factor in the efficient operationof the oil burner since it retains the heat and concentrates it in thedesired manner for best results and saving of oil fuel.

Having thus described myinvent-ion, I claim:

1. The combination with a heating plant including a furnace having agrate, of an oil burner comprising an elongated, imperforate walled opentop receptacle adapted to seat on said grate, a gravity oil feed pipeextending through the'wall. of said furnace and down in said receptacle,said pipe terminating in a pair of convolutions conforming to the wallof the receptacle with the lower convolution resting on the bottom ofsaid receptacle, said lower convolution having a plurality of inwardlyand upwardly extending oil discharge outlets, and a pair of air inletslocated respectively at opposite ends of said receptacle, one of saidinlets be ing in close proximity to the bottom of the receptacle and theother in close proximity to the top edge thereof, whereby completecombustion is promoted and "smoke and noise eliminated.

2. An oil burner for heaters comprising an imperforate walled open topreceptacle, a gravity feed oil pipe extending down into said receptacle,and said pipe terminating in two superposed convolutions with the bottomconvolution having a plurality of inward'ly and upwardly extending fueloutlets, oppositely arranged air inlets in the wall of said receptacleadjacent the upper and lower ends of said wall respectively, and saidreceptacle formed of material adaptedto easily become incandescent underheat.
